Description

Technical Field

[0001] The utility model belongs to the field of plasma propulsion aircraft, in particular to a new type of ion wind propulsion aircraft. Background Art

[0002] Ionic wind generated by corona discharge is a novel aircraft propulsion method that can be applied to the design and development of ultra-lightweight unmanned aerial vehicles (UAVs) without mechanical rotating parts. Compared with traditional aircraft propulsion methods, ionic wind aircraft offer advantages such as low noise, no motor, reduced greenhouse gas emissions, and no mechanical wear, and thus have enormous potential for application in the aerospace field. During the corona discharge process, charged particles are subjected to the Coulomb force in an applied electric field, colliding with neutral molecules and exchanging momentum. The neutral molecules and atoms gain momentum through collisions and move along with the charged particles, generating ionic wind.

[0003] Lightweight ion wind aircraft have a simpler assembly structure and lack propellers and other easily worn parts, thus reducing manufacturing and operating costs and achieving higher economic benefits. Battery energy storage eliminates the need for fuel combustion, reducing emissions of greenhouse gases such as carbon dioxide and achieving higher environmental impacts. Furthermore, silent flight is possible. As a new aviation propulsion method with low greenhouse gas emissions, ion wind propulsion has great potential for development. The field of ion wind propulsion and ion wind aircraft is in its infancy. The new ion wind propulsion aircraft proposed in this utility model has multiple power components, high propulsion performance, a high payload ratio, and strong operational stability.

[0004] The principle of ion wind is that corona discharge occurs between an electrode with a sharp curved surface (a needle or thin wire) with an extremely small radius of curvature and an electrode with a larger, uncurved curved surface or a flat surface. The electrode with the smaller radius of curvature is called the emitter and can be positively or negatively charged. The other electrode is called the collector and is generally grounded. Because the onset voltage of negative corona discharge is lower than that of positive corona discharge, the positive ions accumulated in the corona region increase the electric field strength near the corona electrode. Furthermore, negative DC corona discharge has greater stability and uniformity. Therefore, using negative corona discharge to generate ion wind is more effective, and this aircraft uses negative corona discharge. The mechanism of negative corona discharge is as follows: when the emitter voltage is high enough, causing the electric field near its electrode to exceed the critical discharge field strength of the atmosphere, air molecules near the emitter are ionized into electrons and positive ions, forming an ionization zone. At this time, if the emitter voltage is negative, the electrons and negative ions drift toward the collector under the action of the electric field force. This moving area is called the drift zone. In the drift region, electrons and negative ions are accelerated by the electric field during the drift process, and collide with neutral particles and move toward the collector together, thereby generating ion wind. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model aims to provide an ion wind propulsion aircraft. This aircraft features a wing-body fusion layout, a lightweight design, a light structure, and low drag. The aircraft incorporates numerous power components to provide powerful propulsion. The ducted ion wind propulsion components utilize a novel electrode array structure, which not only increases propulsion but also assists in controlling the aircraft's attitude.

[0006] The utility model is achieved through the following technical solutions.

[0007] An ion wind propulsion aircraft comprises an air inlet, a main propulsion ion wind power component, a ducted ion wind power component, a battery and equipment compartment, an aircraft body, and rudders. The aircraft body presents a wing-body fusion layout and is provided with winglets. The air inlets are arranged on both sides of the lower central axis in front of the aircraft body. The main propulsion ion wind power component is arranged on the rear side of the aircraft central axis and is integrated with the aircraft body. The air inlet is connected to the main propulsion ion wind power component. The ducted ion wind power component is symmetrically arranged on both sides of the central axis along the wing direction on the upper rear side of the aircraft body. The battery and equipment compartment is arranged inside the front middle of the ion wind aircraft body and in the middle of the two air inlets. The rudders are symmetrically arranged along the central axis behind the aircraft body. Power supply batteries, communication and boost components are arranged in the battery and equipment compartment.

[0008] Furthermore, the air inlet is arc-shaped and located on the lower side of the nose and passes through to the main propulsion ion wind power component. It is mainly to cooperate with the main propulsion ion wind power component to compress the air to form another "duct" and the generation of ion wind requires sufficient air for momentum exchange.

[0009] Furthermore, the main propulsion ion wind power component is arranged on the rear side of the central axis of the aircraft body and is integrated into the aircraft body. The main propulsion ion wind power component includes two layers of upper and lower insulating plywood and electrode pairs. The overall shape of the two layers of insulating plywood is a contracted form. An array of electrode pairs is arranged inside the main propulsion ion wind power component. The electrode pairs include an emitter and a collector. The emitter is a filament electrode coated with graphene, and the collector is a low-resistance wing-shaped electrode. The electrode pairs are arranged along the incoming flow direction, with a total of 9 pairs arranged, and every 3 pairs of electrode pairs forming a column.

[0010] Furthermore, in order to cooperate with the contraction of the clamping plate to generate stronger power, each row of collectors is arranged to reduce the chord length of the airfoil in the direction of the incoming flow.

[0011] Furthermore, there are a total of 8 ducted ion wind power components, which are arranged on the wings of the ion wind aircraft near the trailing edge and symmetrically arranged on both sides of the center line of the ion wind propulsion aircraft, with 4 on each side.

[0012] Furthermore, an array of electrode pairs is arranged inside the ducted ion wind power component. The electrode pair includes an emitter and a collector. The emitter is a filament electrode coated with graphene, and the collector is a low-resistance wing-shaped electrode. They are arranged along the incoming flow direction in two rows, with four electrode pairs in each row.

[0013] Furthermore, to match the shape of the duct, each column of electrode pairs has two longer ones in the middle and two shorter ones on the sides.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] The utility model is a combination of multi-combination ion wind propulsion, which combines the main propulsion ion wind power and the distributed ducted ion wind power. It has a novel form and layout, and its power is more significant than that of traditional ion wind aircraft propulsion. The aircraft adopts only partial forms of fully movable control rudders, and the weight reduction effect is obvious.

[0016] The ion wind propulsion power proposed by the present invention has an array arrangement of electrode pairs on a two-dimensional surface, and a spatial arrangement of multi-layer array electrode pairs is designed on this basis, which improves the energy feed efficiency of the propulsion power and is "contracted" with stronger power. The ion wind propulsion device has no mechanical transmission parts, has low noise, and utilizes electrical energy to convert into kinetic energy, resulting in less pollution.

[0017] The ion wind aircraft proposed in this utility model utilizes a wing-body fusion structure to achieve better aerodynamic performance. The advantages of a wing-body fusion structure are light structure, large volume, and low drag. The main propulsion ion wind is integrated into the aircraft, and the air inlet is arranged to pass through the main propulsion ion wind power source, which better facilitates the generation of ion wind and exchanges momentum with the air. It also cooperates with the main propulsion ion wind power source to further compress the air to form another "duct". BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0026] like Figure 1 As shown, an ion wind propulsion aircraft includes an air inlet 1, a main propulsion ion wind power component 2, a ducted ion wind power component 3, a battery and equipment compartment 4, an aircraft body 5, and a rudder 6. The aircraft body 5 presents a wing-body fusion layout with winglets. The air inlet 1 is arranged on both sides of the lower central axis in front of the aircraft body 5. The main propulsion ion wind power component 2 is arranged on the rear side of the aircraft central axis and is integrated with the aircraft body 5. The air inlet 1 is connected to the main propulsion ion wind power component 2. The ducted ion wind power component 3 is symmetrically arranged on both sides of the central axis along the wing direction on the upper rear side of the aircraft body 5. The battery and equipment compartment 4 is arranged inside the front of the ion wind aircraft body 5 and in the middle of the two air inlets 1. The rudder 6 is symmetrically arranged on the central axis behind the aircraft body 5. The battery and equipment compartment 4 is provided with power supply batteries, communication and boosting components to provide power for the aircraft ion wind generation, control its flight attitude and boost the emitter 7 generated by the ion wind.

[0027] Furthermore, the air inlet 1 is arc-shaped and located at the lower side of the nose and passes through to the main propulsion ion wind power component 2. It is mainly to cooperate with the main propulsion ion wind power component 2 to compress the air to form another "duct" and the generation of ion wind requires sufficient air for momentum exchange.

[0028] Furthermore, the main propulsion ion wind power component 2 is arranged at the rear side of the central axis of the aircraft body 5 and integrated into the aircraft body 5, such as Figure 2 As shown, the main propulsion ion wind power component 2 includes two layers of upper and lower insulating plywood and electrode pairs. The overall shape of the two layers of insulating plywood is a contracted form. An array of electrode pairs is arranged inside the main propulsion ion wind power component 2. The electrode pairs include an emitter 7 and a collector 8. The emitter 7 is a filamentary copper wire coated with graphene, and the collector 8 is a low-drag airfoil made of aluminum film. The electrode pairs are arranged along the incoming flow direction, with a total of 9 pairs arranged, and every 3 pairs of electrode pairs form a column.

[0029] like Figure 3As shown, the ion wind generation mechanism of an ion wind propulsion aircraft is as follows: when the voltage of the emitter 7 is high enough, so that the electric field near its electrode exceeds the critical discharge electric field strength of the atmosphere, the air molecules near the emitter 7 will be ionized into electrons and positive ions, forming an ionization zone. The emitter 7 is a negative voltage. Under the action of the electric field force, the electrons and negative ions will drift toward the collector 8. This moving area is called the drift zone. In the drift zone, the electrons and negative ions are accelerated by the electric field during the drift process, and collide with neutral particles to move together toward the collector 8, thereby generating ion wind.

[0030] Furthermore, in order to form a stronger power by cooperating with the shrinking clamps, each row of collectors 8 is arranged to reduce the chord length of the airfoil in the incoming flow direction.

[0031] Further, if Figure 4 As shown, there are a total of eight ducted ion wind power components 3, which are arranged on the wings of the aircraft body 5 near the trailing edge and symmetrically along the center line of the aircraft body 5, with four components arranged on each side.

[0032] Furthermore, an array electrode pair is arranged inside the ducted ion wind power component 3. The electrode pair includes an emitter 7 and a collector 8. The emitter 7 is a filament electrode coated with graphene, and the collector 8 is a low-resistance airfoil electrode. They are arranged in two rows along the incoming flow direction, with four electrode pairs in each row.

[0033] Furthermore, to match the shape of the duct, each column of electrode pairs has two longer ones in the middle and two shorter ones on the sides.

[0034] A support portion 9 supports the ducted ion wind power component 3 arranged on the upper trailing edge of the aircraft body 5. In addition to generating power, the ion wind power component 3 also assists in controlling the attitude change of the aircraft.

[0035] like Figure 5 As shown, an ion wind propulsion aircraft is in an ascending and tilting state, with two rudder surfaces 6 tilted upward. The ion wind generated by the aircraft's distributed ducted ion wind power component 3 has an impact on the rudder surfaces and will increase their tilting torque. When descending, the rudder surfaces 6 will tilt downward at the same time, and the rudder surfaces will not tilt during level flight.

[0036] like Figure 6 As shown, an ion wind propulsion aircraft is in a left yaw state, with the left rudder 6 tilted upward and the right rudder 6 tilted downward. While the distributed ducted ion wind power components 3 save power, the four ducted ion wind power components 3 on the right side appropriately increase the power, while the four ducted ion wind power components 3 on the left side reduce the power. This can increase the steering torque and increase maneuverability. The opposite is true for right yaw.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
